Systematic review of Late Jurassic sauropods from the Museu Geológico collections (Lisboa, Portugal)

The Museu Geológico collections house some of the first sauropod references of the Lusitanian Basin Upper Jurassic record, including the Lourinhasaurus alenquerensis and Lusotitan atalaiensis lectotypes, previously considered as new species of the Apatosaurus and Brachiosaurus genera, respectively. Several fragmentary specimens have been classical referred to those taxa, but the most part of these systematic attributions are not supported herein, excluding a caudal vertebra from Maceira (MG 8804) considered as cf. Lusotitan atalaiensis. From the material housed in the Museu Geológico were identified basal eusauropods (indeterminate eusauropods and turiasaurs) and neosauropods (indeterminate neosauropods, diplodods and camarasaurids and basal titanosauriforms). Middle caudal vertebrae with lateral fossae, ventral hollow border by pronounced ventrolateral crests and quadrangular cross-section suggest for the presence of diplodocine diplodocids in north area of the Lusitanian Basin Central Sector during the Late Jurassic. A humerus collected from Praia dos Frades (MG 4976) is attributed to cf. Duriatitan humerocristatus suggesting the presence of shared sauropod forms between the Portugal and United Kingdom during the Late Jurassic. Duriatitan is an indeterminate member of Eusauropoda and the discovery of new material in both territories is necessary to confirm this systematic approach. The studied material is in according with the previous recorded paleobiodiversity for the sauropod clade during the Portuguese Late Jurassic, which includes basal eusauropods (including turiasaurs), diplodocids and macronarians (including camarasaurids and basal titanosauriforms).

La compétence sociale des enfants et des adolescents atteints de déficience motrice cérébrale

Les enfants atteints de déficience motrice cérébrale (DMC) intégrés en milieu scolaire ordinaire vivent davantage de difficultés relatives à la compétence sociale que les autres enfants. En lien avec le modèle SOCIAL de Beauchamp et Anderson (2010) (The socio-cognitive integration of abilities model), deux questions sont abordées afin de comprendre ces difficultés. Dans le premier article, les attributions d’intentions (AI) hostiles sont mesurées par le Home Interview with Child (HIWC), un ensemble de vignettes représentants des situations sociales ambigües. Les résultats montrent que l’acceptation sociale, plus que le statut de naissance, est associé à l’hostilité des AI à 15 ans. Les enfants rejetés et populaires ont un niveau d’AI hostiles supérieur aux enfants de la catégorie d’acceptation sociale moyenne. Il est proposé que l’acceptation sociale soit un médiateur important à considérer dans le développement d’un biais d’AI hostile chez les enfants atteints de DMC. Dans le deuxième article, la dominance sociale (i.e., une forme de leadership) est évaluée dans une situation de résolution de problème en équipe. Les comportements relatifs à la dominance sociale (i.e., les comportements prosociaux et coercitifs) sont codifiés à l’aide d’une grille créée et validée pour cette étude. Les résultats révèlent que, sans égard au score d’acceptation sociale, les enfants atteints de DMC effectuent significativement moins de comportements prosociaux et coercitifs que les enfants sans DMC au cours de la résolution de problème. De plus, leur équipe de travail émet un nombre de comportements prosociaux et coercitifs inférieur à celui observé dans l’équipe des deux enfants témoins. Les difficultés de compétence sociale observées chez les jeunes atteints de DMC pourraient être en partie expliquées par une faible dominance sociale lors d’activités sollicitant les fonctions exécutives. Enfin, les deux articles présentés permettent d’explorer de nouvelles avenues pour comprendre et soutenir le développement de la compétence sociale chez les enfants et les adolescents atteints de DMC. Les interventions auprès de cette clientèle devraient avoir lieu tôt et devraient cibler autant les habiletés motrices de ces jeunes que leur compétence sociale, avant que des signaux clairs ne compromettent déjà leur expérience sociale globale en milieu scolaire ordinaire.

Saúde bucal no Programa de Saúde da Família : o caso do Distrito Sanitário Norte de Natal-RN

The inclusion of the dentist in the Family Health Program (FHP) teams designates a reorganization of the mouth health care in your country and establishes a new scenario in Brazilian odontology, through of a new way to organize the basic health care, creating conditions to consolidate in mouth health practice actions, in the level of the basic attention, the validation of Unique Health System (UHS) constitutional principles. The purpose of this research is to verify if the actuation of mouth health teams (MHT) dentists, in Natal city north sanitary district, is tuned with FHP goals.The target research population was composed by all dentists working in Basic Health Units (BHU) of Natal north sanitary district. Fifth-eight questionnaires were applied and using open and closed questions we look for identify the functional characteristics of each BHU, the dentists professional attributions on each BHU, as well as the clinical procedures that they execute. This research also searched to identify the factors that facilitate and/or difficult the inclusion process and the dentists activities performance on these BHUs, as well as the necessary actions to north sanitary district MHTs to fulfill the objectives proposed by FHP. The results point that the inclusion of mouth health actions in north sanitary district FHPs brought the incorporation of new values to the used practices. Whoever, its necessary a more frequent evaluation of the carried actions, in a way they can be adapted to the real community necessities, and, is fundamental the data accompaniment, for that these serve of base for planning and redirecting activities, in a way that we do not have only a reproduction of traditional practices, fragmented and isolated, but a truly substitution of the traditional practices and a new way of promoting health

L’enseignement de l’histoire et l’apprentissage de la pensée historique : Description des fondements et des pratiques d’enseignants d’histoire de troisième et quatrième années du secondaire, des écoles francophones du Québec

Les prescrits didactiques et le programme d’Histoire et éducation à la citoyenneté (Gouvernement du Québec, 2007) défendent actuellement des pratiques d’enseignement visant l’apprentissage de la pensée historique. Un apprentissage qui est défini comme une activité intellectuelle inscrite dans une démarche de résolution de problème, permettant de développer une compréhension plus approfondie des réalités sociales dans la perspective du temps (Martineau, 2010). Toutefois, les recherches indiquent que cet apprentissage serait variablement intégré aux pratiques effectives dans les classes d’histoire (Levstik, 2008), notamment au Québec (Boutonnet, 2013; Moisan, 2010). À cet égard, il semblerait y avoir un écart entre les finalités auxquelles les enseignants adhèrent et les situations d’enseignement-apprentissage qu’ils mettent en œuvre. Pour mettre en lumière cette variabilité, nous avons réalisé une recherche exploratoire visant à décrire les pratiques d’enseignement en histoire en troisième et en quatrième années du secondaire. À cette fin, nous avons eu recours aux théories des représentations sociales (Moscovici, 1976) et de l’attribution (Deschamps, 1996) permettant de recenser, dans le savoir commun des enseignants d’histoire, des éléments relatifs à l’apprentissage de la pensée historique. Ce savoir a été analysé en fonction de quatre types de variables : l’opinion, les dispositifs d’enseignement, les attributions et les attitudes individuelles à l’égard de l’apprentissage de la pensée historique. Les données ont été recueillies auprès d’un échantillon de convenance de huit enseignants, et elles ont été analysées dans le cadre d’une approche lexicométrique. La procédure de cueillette a consisté à réaliser quatre entrevues auprès de chacun de ces enseignants, lors des phases préactive et postactive de trois situations d’enseignement-apprentissage, pour identifier par la récurrence des discours des propriétés invariantes. Les données ont été interprétées en fonction de deux types de fondement théorique, relatifs aux théories de l’apprentissage, illustrant différentes manières d’apprendre à penser historiquement, et aux modèles de pratique, décrivant des dispositifs séquencés d’enseignement associés à cet apprentissage. De manière générale, les résultats révèlent la prédominance des théories de l’apprentissage de sens commun, socioconstructiviste et cognitivo-rationaliste, ainsi que des modèles de pratique fondés sur la conceptualisation et le tâtonnement empirique. Même si cette recherche ne peut être considérée représentative, elle a comme principale retombée scientifique de livrer une description de pratiques nuancée, exprimant différentes modulations de l’apprentissage de la pensée historique au niveau des pratiques. Cette recherche contribue à alimenter la réflexion auprès des chercheurs, des formateurs et des enseignants qui pourront mettre en perspective les pratiques actuelles relatives à un apprentissage des plus importants en histoire.

A produção do mobiliário urbano nos espaços públicos :o desenho do mobiliário urbano nos projetos de reordenamento das orlas do Rio Grande do Norte

This work aims to analyze and evaluate the Urban furniture designed to public areas according to the Revitalization planning for Rio Grande do Norte coastland, defining visual relations among urban elements in the landscape of revitalized public urban areas with cultural, paisagistic and touristic values and the design process used for developing urban furniture to those areas, observing the incoming consequences use to that process in a specific urban context which alters use, functions, cultural images as well as social values attributed to each particular place. Environmental perceptions, legibility of local cultural references and their representation through the design of urban elements, act in a positive or negative manner over the inhabitants cognition process of some particular revitalized area, determining new use and attributions to those areas. Designs for coastal urban interventions try excessively to standardize technical media, construction materials and planning configurations, creating artificial sceneries that segregates users, imposing new structures and usage, generating, consequently, the so called non-places and burlesque regionalism. The research is divided into 4 chapters: 1) Theoretical support (Industrial design; Urban furniture; Public urban spaces; Urban image and environmental perception; Urban occupation and interventions in coastland areas); 2) Methodological procedures and data collection; 3) Analysis of Rio Grande do Norte coastal areas and their urban interventions; 4) Final considerations and Industrial Design contributions to the subject

The Role of College Students' Perceptions of Effort Source on Self-Evaluations of Academic Ability

In the present studies I investigated whether college students’ perceptions of effort source influenced their perceptions of the relation between levels of their own effort and ability in mathematics. In Study 1 (N = 210), I found using hypothetical vignettes that perceptions of task-elicited effort (i.e., effort that arises due to the subjective difficulty or ease of the task) led to perceptions of an inverse relation between one’s effort and ability, and perceptions of self-initiated effort (i.e., effort that arises due to one’s own motivation or lack of motivation) led to perceptions of a positive relation between one’s effort and ability, consistent with my hypotheses and prior research. In Study 2 (N = 160), participants completed an academic task and I used open-ended questions to manipulate their perceptions of effort source. I found that participants in the task-elicited condition endorsed no overall relation between effort and ability, and participants in the self-initiated condition endorsed an overall inverse relation, which is inconsistent with my hypotheses and prior research. Possible explanations for the findings, as well as broader theoretical and educational implications are discussed.

The emergence and evolution of optimistic expectations in schoolchildren

When we study optimism in children, we note the temporary emergence of a bias that leads them to make optimistic predictions. In this study we intend to learn more about changes that can be observed in the optimistic bias of 6- to 12-year old schoolchildren when they predict future events, and in the way they justify those predictions. A total of 77 pupils participated in this study; we evaluated each one of them individually with a Piagetian interview, asking them to formulate predictions about a series of hypothetical situations. After analyzing whether a child's prediction implied that the situation would maintain itself or would change for better or for worse, we classified the justifications they provided for their predictions. Results show that these subjects regarded positive change as more likely in the case of psychological or hybrid events than for purely biological ones, and that younger children tended to display a greater bias in favor of the likelihood of positive change. These younger children justified their predictions stating that nature or the passing of time could be responsible for the changes, without needing further intervention on the part of other agents. Older children, on the other hand, tended to provide similar kinds of explanations to justify their expectation of stasis.

Género, idade e antiguidade na empresa : Uma análise comparativa de contracto psicológico.

Poucos são os estudos que relacionam variáveis de nível individual como o género, idade e antiguidade na empresa, com a percepção de contracto psicológico, no entanto para além destas variáveis moldarem o conteúdo do contracto psicológico (Guest, 2004), parecem também determinar diferentes valores e interesses de trabalho (Elizur, 1994; Bal, Lange, Jansen e Velde, 2008). Tais evidências chamam a atenção das organizações para o facto de diferentes grupos de trabalhadores apresentarem diferentes percepções de contracto psicológico, podendo consequentemente responder de diferente forma às mesmas políticas organizacionais (Freese & Schalk, 1996). O presente estudo procurou perceber se diferentes grupos de trabalhadores, de diferentes géneros, idades e antiguidades apresentam diferentes percepções de contracto psicológico, procurando posteriormente aceder às causas percebidas de quebra de contracto (Renegação, Disrupção, Incongruência e Anulação), mencionadas na literatura por Rousseau (1995) e Morrinson e Robinson (1997). Foi utilizada uma amostra, recolhida por conveniência, de 83 participantes pertencentes a uma empresa do sector alimentar, constituída por 57,8% de mulheres e 42,2% de homens. Em média possuem 37 anos de idade e 9 anos de antiguidade na empresa. Foi aplicado um questionário, desenvolvido por Lester, Turnley, Bloodgood e Bolino (2002) constituído por diferentes dimensões (Compensação, Recompensas com base na performance, Características da Função, Progressão e Desenvolvimento, Recursos e Relação Laboral) que constituem o contracto psicológico, assim como pelas diferentes causas percebidas de incumprimento da promessa. Após uma análise factorial, foram extraídos 5 factores (Características da Função, Relação Laboral, Compensação, Recursos e Progressão e Recompensas com base na performance). Os resultados demonstraram que os trabalhadores mais velhos percepcionam que a sua empresa lhes proporciona menos do que o prometido relativamente à Compensação, resultados igualmente obtidos para os trabalhadores com mais antiguidade na empresa. Uma posterior análise correlacional demonstrou que a idade está associada com a antiguidade dos trabalhadores. Quanto à causa percebida de incumprimento, os resultados evidenciaram que a maioria dos trabalhadores atribui o incumprimento das promessas à Renegação. Por outras palavras, os trabalhadores entendem que a sua organização não cumpriu as promessas que lhes fez, simplesmente porque assim o quis.

Dia da mãe : “Virtuosidades ao serviço do desempenho”

O Capital psicológico positivo (CPP) são capacidades psicológicas que definem um estado de desenvolvimento psicológico positivo em que a pessoa se caracteriza por: a) apresentar uma elevada confiança para despender o esforço necessário para ser bem sucedida em tarefas desafiantes; b) fazer atribuições positivas acerca dos acontecimentos que vão suceder no presente e no futuro; c) manifestar perseverança em relação aos objectivos definidos, e, quando necessário mostrar-se capaz de redireccionar os meios para atingir os fins; d) revelar capacidade para recuperar de adversidades. As capacidades psicológicas positivas que melhor definem os critérios anteriormente definidos são: auto-confiança, optimismo, esperança e resiliência. Neste estudo foram recolhidos dados do nível Psycap de 100 vendedores e avaliações de CCO em cinco facetas (harmonia interpessoal, espírito de iniciativa, conscienciosidade, identificação com a organização e orientação para os clientes) e o Output individual numa dada tarefa, tendo-se obtido 100 díades. Explorou-se neste estudo a relação existente entre o PsyCap e dois tipos de desempenho (intra e extra papel) e a relação entre o desempenho contextual e de tarefa. Os resultados indicam que o PsyCap se relaciona com os dois tipos de desempenho, bem como a existência de uma relação entre desempenho contextual e tarefa. Considerações e implicações dos resultados são discutidas ao longo do trabalho.

Conducta prosocial y autoatribuciones académicas en Educación Secundaria Obligatoria

Este estudio presenta los resultados sobre la relación que existe entre las autoatribuciones académicas en lenguaje y matemáticas en una muestra de 2.022 estudiantes de Educación Secundaria de 12 a 16 años. Los adolescentes fueron seleccionados aleatoriamente de 20 escuelas urbanas y rurales en las provincias de Alicante y Murcia, España. La conducta prosocial fue codificada con el Teenage Inventory of Social Skills y las autoatribuciones académicas fueron medidas mediante la Escala de Atribución Causal de Sydney (Sydney Attribution Scale, SAS; Marsh, 1984). El 17.35% de estudiantes de ESO fueron identificados como prosociales. Los chicos de 2º de ESO y las chicas de 4º de ESO presentaron la menor y mayor prevalencia puntual de conducta prosocial, respectivamente. Respecto a la asignatura de lenguaje, los estudiantes prosociales atribuyen significativamente el éxito a la capacidad, el esfuerzo y, en menor medida, a causas externas. En cuanto a la asignatura de matemáticas, los estudiantes prosociales atribuyeron el éxito significativamente más al esfuerzo y significativamente menos a causas externas, mientras que atribuyeron el fracaso significativamente más a la falta de esfuerzo. Además, los datos han permitido crear un modelo de regresión logística que permite hacer estimaciones correctas respecto a la probabilidad de éxito académico en matemáticas, en lenguaje y en todas las asignaturas aprobadas en estudiantes prosociales de E.S.O. a partir de las puntuaciones en atribuciones académicas.

A ansiedade infantil : vulnerabilidades da criança e influência dos pais

Tese de Doutoramento em Psicologia na área de especialidade Psicologia Clínica

Causal factors of anxiety symptoms in children

Aim: The present work aimed to investigate the impact of the child’s cognitions associated with ambiguous stimuli that refer to anxiety, both parents’ fears and anxiety, and parents’ attributions to the child’s interpretations of ambiguous stimuli on child anxiety. The influence of parental modelling on child’s cognitions was also analyzed. Method: The final sample was composed of 111 children (62 boys; 49 girls) with ages between 10 and 11 years (M = 10.6, SD = 0.5) from a community population, and both their parents. The variables identified as most significant were included in a predictive model of anxiety. Results: Results revealed the children’s thoughts (positive and negative) related to ambiguous stimuli that describe anxiety situations. Parents’ fears and mothers’ anxiety significantly predict children’s anxiety. Those variables explain 29% of the variance in children general anxiety. No evidence was found for a direct parental modeling of child cognitions. Conclusion: Children’s positive thoughts seem to be cognitive aspects that buffer against anxiety. Negative thoughts are vulnerability factors for the development of child anxiety. Parents’ fears and anxiety should be analyzed in separate as they have distinct influences over children’s anxiety. Mothers’ fears contribute to children’s anxiety by reducing it, revealing a possible protective effect. It is suggested that the contribution of both parents’ fears to children’s anxiety may be interpreted acknowledging the existence of “psychological and/or behavioral filters”. Mothers’ filters seem to be well developed while fathers’ filters seem to be compromised. The contribution of mothers’ anxiety (but not fathers’ anxiety) to children’s anxiety is also understood in light of the possible existence of a “proximity space” between the child and parents, which is wider with mothers than with fathers.
